Abstract

The invention provides an overload prevention combined type variable spring supporter and hanger utilizing a threaded rod to lock. The overload prevention combined type variable spring supporter and hanger structurally comprises an upper cover plate, a spring pressure plate, a spring, a spring housing and a lower cover plate, wherein the spring pressure plate is arranged between the upper cover plate and the lower cover plate; the spring is mounted between the lower surface of the spring pressure plate and the upper surface of the lower cover plate; the spring housing is arranged outside the spring; the upper end of the spring housing is connected with and fixed to the upper cover plate; the lower end of the spring housing is connected with and fixed to the lower cover plate; one of two locking bolts penetrate through a hole in the left side of the upper cover plate, a bayonet in the left side of the spring pressure plate, and a hole in the left side of the lower cover plate; and the other locking bolt penetrates through a hole in the right side of the upper cover plate, a bayonet in the right side of the spring pressure plate, and a hole in the right side of the lower cover plate.The overload prevention combined type variable spring supporter has the advantages that (1) precise locking can be realized according to a measured value, and error influence is avoided; (2) a setting value can be modified, no replacement is required, and the cost is reduced; (3) locking again can be realized during overhaul and the operation is facilitated; and (4) with the adoption of a combined structure, the service life of a product is prolonged.

Description

technical field [0001] The invention relates to an anti-overload combined variable spring support hanger adopting screw locking, which belongs to the technical field of pipeline and equipment support. Background technique [0002] The variable spring support and hanger is mainly used for the support of thermal pipelines and equipment that require vertical displacement. It can adapt to the requirements of changes in the displacement of pipelines and equipment, and provide support and protection for pipelines and equipment. The traditional variable spring support and hanger is locked by a pin, and the locked position is determined by theoretical calculation, but due to the manufacturing error of the spring, the spring cannot be locked precisely at the design position, and once locked, its position cannot be changed; due to field equipment parameters The adjustment often needs to change the setting value of the spring support and hanger. At this time, it can only be remanufactu...
